Does the new Facebook leave out Internet Explorer 6 users?

This week, Facebook will switch all of its users — happy or not — to a new, redesigned site.

The “new” Facebook, though, does not seem to be compatible with Internet Explorer 6.

Users who try to access the “new” Facebook using the browser are redirected to the old design and told that, “Sorry, the new facebook is temporarily disabled.”

The page then suggests that users may want to upgrade their browsers — to Internet Explorer 7 — or switch to Firefox, Safari, or Flock.

Granted Internet Explorer 6 was launched in 2001. Still, it remains heavily used. Net Applications estimates it is the second most popular browser, after Internet Explorer 7, with roughly 25 percent of the market.

A Facebook spokesman did not respond to a call and e-mail seeking comment this afternoon.

UPDATE: Facebook Spokeswoman Meredith Chin said that while the “new” Facebook is not currently compatible with Internet Explorer 6, the company is working on changing that and it should be compatible “in the coming days.”
